Arsenal manager Arsène Wenger has challenged his side to fight their way back
to form after seeing their Premier League aspirations suffer with a home
defeat to Manchester City.

Arsenal – who must do without midfielder Mikel Arteta for up to a month with a calf injury – have to regroup quickly for an FA Cup third-round replay against Swansea on Wednesday night, when Wenger is expecting the required response.

"We have to fight to do as well as possible until the end of the season," said Wenger. "I feel we need to find in this kind of game more defensive stability.

"The way we gave the ball away, it was a combination of a lack of concentration and a bit of awareness."

City had been handed an early advantage when referee Mike Dean sent off Arsenal defender Koscielny for wrestling Edin Dzeko to the floor after just 10 minutes.

Although the Bosnian saw his penalty saved, via the post as the ball ran back along the goalline to Wojciech Szczesny, City – who last won in the league at Arsenal in 1975 – took command with first-half goals from James Milner and then a tap-in for Dzeko after Carlos Tévez's shot was parried.
